See these same sort of 'Bren' posts over and 1addicts and e90. Numbers are always higher than anyone else gets, his supporters are fanatical. but never any logs posted. Why?

Never any posts from Bren either. Is he actually a member on BB?

I've had both a Bren & ProTuning Freaks tune. IT wasn't a fair comparison because Jake was only able to street tune my car in 98* weather, but @bobS had his car tuned at EFI Logics & then Bren, so he can better testify to the difference.

I've also shared a few logs (93 & E85 tunes), so I'm not sure what you're talking about

Said this already, nobody gives Terry or any other tuner $#@! when they hit new Stock Turbo records, but the minute Bren hits it everybody cries BIG surprise, Bren is probably one of the more skilled tuners on this forum, having experience tuning Subaru's, EVOs, Mini's, AMG Mercedes, various BMWs (S65/S85/S54/S50/N54/N52 and the S1000RR) with N/A, Turbo or S/C setups.

Here's a video of Bren's personal M3 while it was still N/A, it read 422 WHP on his DynaPack and then put down 426 on a DynoJet (so much for "high reading" dyno) and 427 on a DynoDynamics.

Physics can't be tuned around. Stock turbos aren't going to move much over 410g/s of airflow when pushed HARD(16.5psi) where as my stage 2s are moving ~480g/s at only 15psi. A 20%+ increase in airflow is why hybrid turbos are seeing 480-500whp and stock turbos are seeing 20%+ less power. Of course there are a ton of other factors that go into power but the stock turbo are the bottle neck.

Benzy, please don't take any of this personally or the wrong way. You're a really good dude and I'm sure your car is very fast and Bren is a VERY good tuner but there limits to what can be done.

Hey, it was a 460whp stock turbo record. It was on a dynojet and we posted a log to go along with it. I've seen 450whp figures from all the major tuners so it's not like we're outside the ballpark or anything. Just the right combination of small details to push it that last inch.

On the brentuning stuff, to be candid, I've never heard much about it or paid any attention to it. I've never seen a log, never seen any legitimate dynojet runs, etc. I'm sure he's great. But without data it's hard to get anyone's attention these days...

The problem is there aren't a lot of DJ's in the NJ/NY area, which seems to be the only dyno numbers people foolishly accept (I'm in the party of measuring gains, because those should be undisputedly consistent, regardless of which dyno you're on). I could probably get some data logs with 93 octane tune, but that's not what we're interested in so until I get E85 next time you'll have to wait for me or someone else to share data.

Interesting. Everything I have read on the interwebz about Dyno Dymanics dynos is that they are heart breaker dynos. Even more so than mustang dynos. So curious to see it reading basically the same as a dyno jet in this case.

When left in shootout mode sure but there are a ton of modes. You can make a dyno dynamics read whatever you want.

Interesting. Does making them read 'whatever you want' go beyond using the varying corrections? Curious as I had my initial (and will have my follow-up) dyno done on a dyno dynamics. I know the correction used was ATMC1, but am now wondering if there is anything else I should be asking the operator re: how he has it setup.

I'm not an expert on them but because of all the modes that's the reason they have a mode you can't screw with but people don't like it because their numbers are lower than they want. That's the where the heartbreaker part associated with the dyno dynamics comes in.

I'm sure there is a ton of stuff that can be played with Read this:

Chances are, many of you from around the automotive industry have already heard of the ShootOut system when dyno tuning cars. Dyno Dynamics, the manufacturer of Australia’s leading dynamometer brand, has for many years been considered the benchmark for both accuracy and repeatability. Now, after 4 years of effort (not to mention a substantial financial investment), they have just ‘upped the stakes’ - Dyno Dynamics has developed a system that is set to become the industry standard for power comparison. The system is called ShootOut, it is being utilised by a network of accredited Dyno Dynamics equipped workshops across Australia and will soon be available to all customers worldwide.

The ShootOut mode system is not just a hardware or software upgrade – it is a standardised approach to power measurement, designed to ensure that you can take your car to any accredited workshop and get accurate power measurements for your car. The results will be the same regardless of which ShootOut mode accredited workshop you select. This also means that results from different cars, measured on different dynos can be compared much more accurately which opens a lot of insight to power readings.

ShootOut was developed by Dyno Dynamics primarily to eliminate "Operator Technique" and as a tool for measuring horsepower accurately and CONSISTENTLY for ALL Dyno Dynamics dynos with Shootout accreditation. All dynos with Shootout accreditation have been calibrated the same accross the board, and should not vary more than 1% when comparing between Dyno Dynamics dynos.

Ethical standards
All ShootOut workshops must abide by a code of practice. When a company gets its ShootOut accreditation, it is only leasing the right to use the ShootOut mode and the ShootOut logos on the dynos, which are bgasically the physical and interlectual property of Dyno Dynamics. We are bound by a contractual agreement which is renewed on a yearly basis with very strict guidelines and procedures whenever we use the ShootOut logos on printed dyno graphs. If a company does not adhere to these guidelines, and decides to employ "Operator Techniques" and manipulate theShootOut process, Dyno Dynamics will issue the company with a warning. After 3 warnings, the company loses theirShootOut Accreditation. Dyno Dynamics expect Dyno Operators to be honest and follow the required procedures in accordance with the ShootOut Agreement between the operator and Dyno Dynamics.

Proof of integrity
1. All ShootOut graph runs must be supervised by an accredited ShootOut scrutineer.
2. When the Shootineer is confident that the run has been performed to Dyno Dynamics’ ShootOut standards, the approved ShootOut logo will be added to the graph.
3. Test conditions and other data is printed on the lower edge of the graph as further evidence of accuracy.
4. When the graph is printed, the Shootineer will apply the official ShootOut stamp and personally sign it.
5. As final proof, the customer is provided with a checklist to verify that all steps in vehicle preparation for the test have been carried out correctly.

That's not the 426 dynojet graph though where is that which is what I asked for?

I'm not going to comb the internets just because you asked for a dyno sheet; ask @BrenM3

According to the info you posted, it shouldn't matter what mode of Shoot-Out it's in, they should all ready the same

You're the one who used it as support then posted a video showing the dyno dynamics run only supporting part of your statement. I'm asking you to back it up. This is the problem, where is the dynojet sheet?

Perhaps but what I think it means is it should read the same on any dyno as long as it is that same mode.

I took the numbers straight out of the YouTube video description. Now this mightbe a stretch, but I'm pretty confident Bren's got better things to do then lie about numbers on his vendor YouTube channel. That's the dyno sheet that matches up the 422 WHP DynaPack claim in the YouTube description (although the dyno sheet says 313 WTQ & the video description says 304), the Dyno Dynamics graph is in the video and I'm pretty sure Bren can get the DJ graph for you once he gets a chance.

IF you're that impatient, just email/PM him.

I'm not calling him a liar I just have never seen a 426 whp dct m3 on a dynojet... ever.

Bren will check in when he has time it's the weekend he's probably busy or else he would have already posted.

It was in shoot out mode, ALL of the info I'm sharing regarding Bren's tunes are either on his dyno database or the YouTube videos he's posted

That is especially interesting then. I'd be very interested in knowing how a Dyno Dynamics in shootout mode managed to dyno higher than a dyno jet on the same vehicle. The armchair quarterback in me says something is not jiving. But then armchair quarterbacks have that luxury.

here is something interesting, that if true, would explain the seemingly high dyno dynamics number (if in shoot out mode). And you are right, there are different shootout modes - apparently based on engine size and drive train (awd vs. 2 wheel drive).

Anyways, see point 2. It seems like in shootout mode, it estimates the crank horsepower. Which seems to be confirmed by the dynos, the first one is a dyno of a 'normal' run, the next two in shootout mode. Look at the numbers... Now I am not sure if you have the option to display the wheel horsepower as well. If not, it would seems shootout mode would not be the heartbreaker mode, but just a standardized way of doing things.

Also, not certain the dyno in theyoutube video was in shootout mode. As according to what you posted and the screens in the link above, in shootout mode, a shootout graphic is supposed to appear on the graph, which wasn't in the graph in the vid, but maybe those show up after the fact. I dunno. Edit, yes it looks like the logo is added after.

It might be the record, I think it's important to remember that this is a tuner's personal car, so he's going to be a little less "concerned" with pushing the envelope (versus a customer's car). I mean, here's another FBO E92 M3 that put down 418 WHP / 299 WTQ on his Dynapack (vs. Bren's 422 / 304)

I don't really care about his dyno numbers, it's the gains I care about. I had my car pro tuned at efi logics, as @benzy89 said and his tune was night and day to it. Does his dyno read high? Maybe... Is his tune still gaining more hp/tq on his dyne than what you had before? Absolutely... His tune feels amazing.

I'll get numbers from his dyno when I get my stg 2 vtt's and then I'll go to a dynojet and see how it fairs...

People may be confusing shootout and shoot, there are shoot modes like shoot 8f etc. @evolve @Imranevolve knows a lot about this...
